Re: [Amel Yacht Owners] electrolysis on jib furling gearbox? [1 Attachment]
Mohammad Shirloo
Hello
and welcome to the group;
Sorry
to not address you by your name but I did not see your name in the
e-mail.
I
cannot comment on the source of your particular issue. However if you are
connected to shore power in a marina or harbor without a galvanic isolator, you
are exposing the boat to a high risk of electrolysis depending on your
particular location, wiring and boats surrounding you.
I
would highly recommend the installation of a galvanic isolator to prevent
creating an unintended electrical circuit. Olivier recommended the install on
our 54 during the survey. The installation is fairly straight forward and it
took us a couple of hours to get done.
Respectfully;
Mohammad and Aty

Greetings and Happy New Year, I’m new to the group having purchased “Liebling” SM hull #207 In June 2017. Now she is “La Querida” berthed in Moss Landing, California. Over the last several months I noticed something like grease dripping out from the jib furling gearbox and finally dismantled it last weekend. In general it was in reasonable shape for a 20 year old gearbox. However the aluminum disc on the out put shaft showed considerable pitting which I interpret as electrolysis. On my particular box, the aluminum is in contact with a bronze or brass bushing. I did some reading on line and was quite alarmed to learn that neighboring boats and poor grounding of the marina shore power apparently can accelerate electrolysis on a well designed and maintained boat such as our Amels. So two questions:
Thanks in advance. BTW our plans are to cruise to Mexicos west coast after retirement in about 3 years. Saludos a todas! |

Re: Generator charging question
svperegrinus@yahoo.com
Our solar chargers by Genasun are not properly adjustable to the voltages required by Trojan for our AGM batteries. So we disconnect solar when on shorepower to prevent over-voltage charging of full batteries.
We routinely turn on both battery chargers as follows: (1) When charging from the generator. (2) When we will have shore power for only one day or two. Evidently after one hour or less the batteries charge at less than 100 A, and at this point it makes no difference whether you have one or both chargers on. So we routinely turn one off.

Re: Generator charging question
All our chargers, including solar, are set for the same absorption and float voltages...I think you might be asking for trouble of you have them set differently...especially if you are running more than one at a time.

Re: Inverter/Charger wiring advise
John Clark
and now Bill K some more inverter/charger talk:
I opened up the genset control head and traced the out the wiring. There is an earth/bond connection but is is between the two field coils. This means that the green/yellow wires are always 115v different than the hot(brown) or neutral(blue). The genset has been this way since installation many years ago, so it is apparently doing no harm. Since as you pointed out the genset is connected to the bonding system, I will leave the AC safety jumper in place and see how it looks when I fire her up. The inverter will have two connections to the bonding system, one is "pass through" from the AC power supplied by the generator or shore power. The second is the chassis ground that the unit will connect to the AC output only when the inverter is supplying power. John Clark SV Annie SM 37 St. Augustine. |

Re: Bonding wire question
John Clark
That is a good question, and not easy to answer. I will take a look and see if I can run each to ground....that's a pun by the way.
I will be spending some quality time in the ER installing the new inverter/charger this week after the rain passes so I will likely be opening up several of the wire runs to add the new cable. It will be a good opportunity to trace the wires. John

Re: Generator charging question
John Clark
I too was instructed to run both chargers from the generator, also start the 40A then after a minute start the 30A, and when on SP use the 30A alone.
I noticed that my 40A is set for a higher float voltage, just a tad under 28v, while the 30A floats at 26.7v. I have AGMs and the 26.7 sounds more in line with a long term float. John Clark SV Annie SM 37 St. Augustine

Where are you located? A friend of mine repairs circuit boards regardless where they came from. He just fixed the circuit board on my high tech exercise bike that the factory said could not be repaired and no spares were available. Unfortunately he is in Bogota.

Dear Amelians, I had to buy a new PCB board for my ONAN generator which finally seems to work fine for more than just a couple days... I kept my old board, hoping to find someone who knows how to analyze faults and eventually repair this rather expensive part and then keep it as a spare. So does anyone of you know somebody who could do this work? Best regards, Alex, SY NO STRESS AMEL54 #15 |

Re: [Amel Yacht Owners] Coppercoat?
Part of the argument for Copper Coat is their claim you save money not having to haul the boat as often. However, you will still need to haul an Amel to do drive maintenance. Therefore, not much of a savings when you think about it.
Also, the procedure to apply Copper Coat is not something an everyday boat yard does often or knows how to do. It is not as easy to apply as paint.
My 2 cents

Re: Coppercoat?
greatketch@...
Miles,
Coppercoat seems to be one of those things that sailors love to argue over--almost as much as which anchor is best. Some people think it is great stuff, others are very disappointed. Some differences in opinion seem to be varying expectations, and others seem to come from using it in different environments. I have one piece of data, for your "what it is worth" pile... The previous owners of Harmonie put on Coppercoat. Within a year they had it stripped off and went back to a conventional ablative paint. I do not have any other information about the whys or wherefores on the changes, so it's not really a lot of help... I have never been able to assemble data that convinced me one way or the other. It clearly works for some people, and not for others. I am sure that SOME of the failure stories are due to bad application, but I am also sure that not ALL of them are.

Dessalator watermaker diaphragm accumulator
Sv Garulfo
Hi Amelians, The high pressure diaphragm accumulator on our dessalator duo 100 failed due to rust. Amazing for a supposedly stainless steel device 5mm thick. Did anybody else experience that issue? I'm struggling to find an exact replacement from Hydac, their current catalog does not feature the same attachments ends. ( ref is SB0210 - 0,16 E2/302 U - 210HK030) Does anybody have a suitable alternative? Fair winds and fresh water to all! Thomas GARULFO Amel 54#122 Barbados

Re: [Amel Yacht Owners] bow thruster shaft removal tool
greatketch@...
James,
toggle quoted message
Show quoted text
There are three seals involved: -The "outer" seals which do the primary sealing when the thruster is lifted underway, -The "inner" seal which seals when the thruster is lowered, and -The lip seal which keeps water out while moving in between "up" and "down". The "inner seal" (the one you can see inside the cabin), is not really doing any meaningful sealing while the thruster is in the raised position, only when it is down for operation. If your seals are relatively new and are leaking a bit while underway, you can probably fix it by raising the thurster's pinned position a few millimeters and compressing the seals more. You might want to try this before you replace the seals. The foam gaskets that make the lower seal take a bit of a "set" when they are first compressed, so need a bit more compression to stay sealed for the long term. Once you drop the thruster lower unit and lift it up on deck, it is a simple matter to replace the "lower" seals, as well as the others. A general comment from the last service I did on our thruster: The shaft tube was "furry" with glass fibers. They would have torn up the lip seal in very short order, so I ran 800 grit sand paper over the shaft to be sure it was smooth, and then liberally greased it with waterproof silicon grease. Bill Kinney SM160, Harmonie North Bimini, Bahamas ---In amelyachtowners@..., <jamescromie@...> wrote : Thanks for the replies regarding the bow thruster. It was service only a year Ago and had new seals installed, though I noted some water seepage around the inside donut while under sail. It would be nice to change just the inner seals, but I’m concerned that the compression fit of the outer seals may be part of the problem. As far as changing the name, I haven’t gone through the ritual of changing the nam yet ... so everything is still “la Bella Vita “ until that time...

John,
We'll second the vote for Browns. The only downside is that right now they don't have shore power on the docks, so if that is important to you, Bimini Big Game might be the better choice. They are working on it...on island time. Everything else is in very good shape. Bimini Big Game looks nice on a walk through, although this time of year (between fishing seasons) everything here is really quiet. Right now there are three boats in Brown's, maybe a half dozen in Bimini Big Game. Might change for the weekend, there is a big wahoo fishing tournament.
If you do come to Brown's and you want the restaurants and bars at Bimini Big Game, they are just a short walk away.
We're pulling out of Brown's tomorrow, and anchoring in Nixons Harbor for a day or two, then heading up to Freeport, then to the Berry Islands... then south... Watch for us on AIS!
All the marinas here have a very strong tidal current that runs through more or less parallel to the slips, so be ready for it. The entrance channel has plenty of water, and the buoys are in place and correctly mark the channel, although they don't match the chart exactly. Trust the buoys more than the chart. Except...there was one errant red nun that was sitting right on top of the sand bar that wasn't on the chart at all, and looked to have drifted in from somewhere else.
Enjoy!
